My boss wants to "get back into programming" by making an internal web application. I've got lots of experience with php and mvc frameworks, but he's doesn't want to learn php, he wants to learn c# as it probably will be more useful to him down the road (I can't disagree.) I think I'll be ok with tutorials and code snippets I find online...
I want to make a deep copy of a LINQ to XML XElement. The reason I want to do this is there are some nodes in the document that I want to create modified copies of (in the same document). I don't see a method to do this. I could convert the element to an XML string and then reparse it, but I'm wondering if there's a better way. ...
I am developing a wizard for a machine that is to be used as a backup of other machines. When it replaces an existing machine, it needs to set its IP address, DNS, WINS, and host name to match the machine being replaced.

All of this is pertaining to WebHttp binding, hosted in a custom Service Host (IIS is not an option at this time).

This code is sensative to the process where it is being run - that is, there are certin methods that should not called if running under ASP.NET. How do you determine if the code is executing in an ASP.NET process? The soluti...
That's a mouthful... Here's the issue, we're doing some client-side validation via AJAX calls to page methods (which are essentially web services). We've also added a drop-down on the page to choose your language and have created a class that inherits from Page that initializes localization based on the drop-down selection. When page ...
For a product in long run (may be 0.5-1 million users) is it good to use java instead of .net from the cost/profitability perspective. To elaborate more..consider web farm scenario in which one will have to purchase windows + Sql server + some antivirus licenses for .net applications. But for java it's almost free. What points should I c...

I have this regex I built and tested in regex buddy. "_ [ 0-9]{10}+ {1}+[ 0-9]{10}+ {2}+[ 0-9]{6}+ {2}[ 0-9]{2}" When I use this in .Net C# I receive the exception "parsing \"_ [ 0-9]{10}+ +[ 0-9]{10}+ +[ 0-9]{6}+ [ 0-9]{2}\" - Nested quantifier +." What does this error mean? Apparently .net doesn't like the expression. Here is ...
I have a .net web-service hosted in IIS 6.0 that periodically fails with an http 500 because a client connects to it with data that does not match the wsdl. Things like having an element specified in a method as being of type int and the inbound xml element contains a decimal number. WSDL element definition: <s:element minOccurs="1" m...

We would like to build something small with IIS and some webform. Here some information you might think are useful: Our controller have Thread of database quer...
Is it possible to somehow mark a System.Array as immutable. When put behind a public-get/private-set they can't be added to, since it requires re-allocation and re-assignment, but a consumer can still set any subscript they wish: public class Immy { public string[] { get; private set; } } I thought the readonly keyword might do t...

For example, if I create an empty text file and rename it to image.jpg, an OutOfMemory Ex...
I am working with some tables where I want the C# class to have a different property name than the underlying table column. However, when I use the Translate method to read the results, the properties that don't match the source name never get populated. Even when I use Linq to generate the SQL. For instance, my table is defined in the ...
